Document properties are some important information contained in Word documents, including title, subject, author, company, keywords, etc. Reading this information can help identify the document, quickly determine the document type or source, and improve the efficiency of document storage and organization. However, if the document properties such as author and company are inappropriate for others to know, you can remove them to protect privacy. This article is going to show how to read or remove document properties in Word documents programmatically using Spire.Doc for Java.

Read Built-in and Custom Properties from Word Documents
There are two types of properties in Word documents: built-in properties and custom properties. Built-in properties are some predefined properties, while custom properties are properties with custom names, types, and values. The detailed steps for reading the two kinds of document properties are as follows:
- Create an object of Document.
- Load a Word document using Document.loadFromFile() method.
- Get all the built-in properties and custom properties using Document.getBuiltinDocumentProperties() method and Document.getCustomDocumentProperties() method.
- Get each built-in property using methods under BuiltinDocumentProperties class.
- Loop through the custom properties to get their name and value using methods under CustomDocumentProperties class.
- Java
import com.spire.doc.BuiltinDocumentProperties;
import com.spire.doc.CustomDocumentProperties;
import com.spire.doc.Document;
public class GetDocumentProperties {
public static void main(String[] args) {
//Create an object of Document
Document document = new Document();
//Load a Word document
document.loadFromFile("C:/Sample.docx");
//Create an object of StringBuilder
StringBuilder properties = new StringBuilder();
//Get all the built-in properties and custom properties
BuiltinDocumentProperties builtinDocumentProperties = document.getBuiltinDocumentProperties();
CustomDocumentProperties customDocumentProperties = document.getCustomDocumentProperties();
//Get each built-in property
String title = builtinDocumentProperties.getTitle();
String subject = builtinDocumentProperties.getSubject();
String author = builtinDocumentProperties.getAuthor();
String manager = builtinDocumentProperties.getManager();
String category = builtinDocumentProperties.getCategory();
String company = builtinDocumentProperties.getCompany();
String keywords = builtinDocumentProperties.getKeywords();
String comments = builtinDocumentProperties.getComments();
//Set string format for displaying
String builtinProperties = String.format("The built-in properties:\r\nTitle: " + title
+ "\r\nSubject: " + subject + "\r\nAuthor: " + author
+ "\r\nManager: " + manager + "\r\nCategory: " + category
+ "\r\nCompany: " + company + "\r\nKeywords: "+ keywords
+ "\r\nComments:" + comments
);
//Add the built-in properties to the StringBuilder object
properties.append(builtinProperties);
//Get each custom property
properties.append("\r\n\r\nThe custom properties:");
for (int i = 0; i < customDocumentProperties.getCount(); i++) {
String customProperties = String.format("\r\n" + customDocumentProperties.get(i).getName() + ": " + document.getCustomDocumentProperties().get(i).getValue());
//Add the custom properties to the StringBuilder object
properties.append(customProperties);
}
//Output the properties of the document
System.out.println(properties);
}
}

Remove Built-in and Custom Properties from Word Documents
Built-in document properties can be removed by setting their values as empty. For custom document properties, we can use the CustomDocumentProperties.get().getName() method to get their name and then use CustomDocumentProperties.remove() method to remove them. The detailed steps are as follows:
- Create an object of Document.
- Load a Word document using Document.loadFromFile() method.
- Get all built-in properties and custom properties using Document.getBuiltinDocumentProperties() method and Document.getCustomDocumentProperties() method.
- Remove the built-in properties by setting their values as empty using methods under BuiltinDocumentProperties class.
- Get the count of custom properties using CustomDocumentProperties.getCount() method.
- Loop through the custom properties, get their names by using CustomDocumentProperties.get().getName() method, and remove each custom property by their name using CustomDocumentProperties.remove() method.
- Save the document using Document.saveToFile() method.
- Java
import com.spire.doc.BuiltinDocumentProperties;
import com.spire.doc.CustomDocumentProperties;
import com.spire.doc.Document;
import com.spire.doc.FileFormat;
public class RemoveDocumentProperties {
public static void main(String[] args) {
//Create an object of Document
Document document = new Document();
//Load a Word document
document.loadFromFile("C:/Sample.docx");
//Get all built-in properties and custom properties
BuiltinDocumentProperties builtinDocumentProperties = document.getBuiltinDocumentProperties();
CustomDocumentProperties customDocumentProperties = document.getCustomDocumentProperties();
//Remove built-in properties by setting their value to empty
builtinDocumentProperties.setTitle("");
builtinDocumentProperties.setSubject("");
builtinDocumentProperties.setAuthor("");
builtinDocumentProperties.setManager("");
builtinDocumentProperties.setCompany("");
builtinDocumentProperties.setCategory("");
builtinDocumentProperties.setKeywords("");
builtinDocumentProperties.setComments("");
//Get the count of custom properties
int count = customDocumentProperties.getCount();
//Loop through the custom properties to remove them
for (int i = count; i > 0; i-- ){
//Get the name of a custom property
String name = customDocumentProperties.get(i-1).getName();
//Remove the custom property by its name
customDocumentProperties.remove(name);
}
//Save the document
document.saveToFile("RemoveDocumentProperties.docx", FileFormat.Auto);
document.dispose();
}
}

Word allows you to create forms that other people can use to enter information. Fillable forms are used for a variety of purposes. Human resources use forms to collect employee and consultant information. Marketing departments use forms to survey customer satisfaction with their products and services. Organizations use forms to register members, students, or clients. Some of the tools you will use when creating a form include:
- Content Controls: The areas where users input information in a form.
- Tables: Tables are used in forms to align text and form fields, and to create borders and boxes.
- Protection: Allows users to populate fields but not to make changes to the rest of the document.
Content controls in Word are containers for content that let users build structured documents. A structured document controls where content appears within the document. There are basically ten types of content controls available in Word 2013. This article focuses on how to create a fillable form in Word consisting of the following seven common content controls using Spire.Doc for Java.
| Content Control | Description |
| Plain Text | A text field limited to plain text, so no formatting can be included. |
| Rich Text | A text field that can contain formatted text or other items, such as tables, pictures, or other content controls. |
| Picture | Accepts a single picture. |
| Drop-Down List | A drop-down list displays a predefined list of items for the user to choose from. |
| Combo Box | A combo box enables users to select a predefined value in a list or type their own value in the text box of the control. |
| Check Box | A check box provides a graphical widget that allows the user to make a binary choice: yes (checked) or no (not checked). |
| Date Picker | Contains a calendar control from which the user can select a date. |

Create a Fillable Form in Word in Java
The StructureDocumentTagInline class provided by Spire.Doc for Java is used to create structured document tags for inline-level structures (DrawingML object, fields, etc.) in a paragraph. The SDTProperties property and the SDTContent property under this class shall be used to specify the properties and content of the current structured document tag. The following are the detailed steps to create a fillable form with content controls in Word.
- Create a Document object.
- Add a section using Document.addSection() method.
- Add a table using Section.addTable() method.
- Add a paragraph to a specific table cell using TableCell.addParagraph() method.
- Create an instance of StructureDocumentTagInline class, and add it to the paragraph as a child object using Paragraph.getChildObjects().add() method.
- Specify the properties and content of the structured document tag using the methods under the SDTProperties property and the SDTContent property of the StructureDocumentTagInline object. The type of the structured document tag is set through SDTProperties.setSDTType() method.
- Prevent users from editing content outside form fields using Document.protect() method.
- Save the document using Document.saveToFile() method.
